I like this idea as well. I saw a good link to a site comparing capabilities of of various java regexp implementations somewhere yesterday, I can't find it now from home. I'll send it out when I get to work. I think its wise to make sure, that if theres a common api, that the user understands that all regexp implementations are not equal in performance, capability and syntax.

This sounds like a very nice grand plan. I support this in spirit at least.

I suspect the answer is the same as last time. The regexp solution is:
Merge ORO/Regexp into each other as Commons-Regexp, with both being a plugin concept Allow a 1.4 plugin concept for it
Daniel's grand plan. Maybe we should more actively try to assist him.

with a "decorator" and (2) this brings up the topic again of whether
or
not it would be a good thing to have a [commons-re] like we have a [commons-logging], a super thin wrapper that delegates to 1.4 or, in this case, [ORO-RE] or [RegExp].

I'm trying to put together a lookup mechanism that is regular
expression
based. For example
Map map = ...;
Bar bar = new Bar();
map.put("^http://foo.bar*",bar);
Bar bar2 = (Bar)map.get("http://foo.bar/bam";);
get("...") would return the bar object. Of course, this could
match
multiple values, as such get("...") could return the first value encountered or a Collection of all the matches encountered.
Collection bars = (Collection)map.get("http://foo.bar/bam";); Iterator iter = bars.iterator(); Bar bar2 = (Bar)iter.next();
Any ideas on how I can throw this together using Commons
Collections
as
a basis? I can live with just >=j2sdk1.4 compatibility. Is this something Commons Collections would like to have available?
